易于实现

已经在西高院实验室进行了试验验证

试验结果满足标准要求。

Abstract

Capacitive current switching test is one of the type tests of the high voltage AC circuit breakers. Due to the capacitive current switching test need power supply with very high capacity

the lab usually adopts the synthesis method to carry out the capacitive current switching test for UHV circuit breaker. The author analyzes the working principle

the advantages and disadvantages of several typical synthesis test circuit recommended by standards

presents a new test circuit of capacitive current switching test for Xi ’an high voltage apparatus research institute Co.

Ltd.（XIHARI）

introduces its working principle

calculates the power frequency voltage change rate

simulates the working process of the test circuit. The equivalence of test circuit is high

and easy to be implemented. The XIHARI laboratory has carried out the capacitive current switching test adopting this test circuit

the test results meet the standard requirements.
